Continuous solid-state polymerization process and reactor column for use therein

摘要

The present invention relates to a continuous solid-state polymerization process for the production of polyamides derived from diamines and dicarboxylic acids, wherein the salts are reacted in a reactor column comprising a continuous multifunctional zone comprising a heating section and a gas-discharge section. polymerized, the heating section comprising a static heat exchanger. The invention also relates to said reactor column and its use in a continuous solid-state polymerization process.
